Hallo ad engineers,


I have two fmcomms1 devices (connected to zedboard) that I want to have synchronized with each other by an external clock source comming from a clock generator. I use the reference design availible on  AD-FMCOMMS1-EBZ Functional Overview [Analog Devices Wiki].


On the schematics you can see a clkin input to the 9523-1, if I connect these two inputs on both devices with my generator, both devices should be synchronized, but if I measure the output channels on both devices connected to adc-9122 they are definitely unsyncron.


Can you advise me on how I can synchronize two fmcomms-1 advices for sure, please?


thank for your efforts.
